Abstract

Compositions and methods for removing phosphates, nitrates and heavy metals from aqueous solutions.

Claims

exact text as granted — not AI-modified
1 . A method of producing a composition capable of removing phosphates, nitrates and heavy metals from a solution, comprising:
 (a) forming a slurry comprising calcium oxide, silicon dioxide, an alkali and a solvent, wherein the molar ratio of the calcium oxide:the silicon dioxide:the alkali ranges from 2.43-2.97:1.12-1.38:0.9-11; and   (b) producing the composition capable of removing phosphates, nitrates and heavy metals from a solution by subjecting the slurry to a hydrothermal process for about 1 to about 6 hours under about 13.5 to 16.5 psi of pressure.   
     
     
         2 .- 27 . (canceled)
